        // 创建场景
        const scene = new THREE.Scene();
        
        // 创建相机
        const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
        camera.position.z = 5;
        
        // 创建渲染器
        const renderer = new THREE.WebGLRenderer();

        // 1. 创建立方体几何体
        const geometry = new THREE.BoxGeometry(2, 2, 2,3,3,3);
        
        // 2. 加载纹理贴图
        const textureLoader = new THREE.TextureLoader();
        // 加载示例图片作为纹理（可替换为自己的图片URL）
        const texture = textureLoader.load('https://qcloud.dpfile.com/pc/_vzQAXVr13f_7iwVuYMN-KZdECsM6WjeAFvnO_6J6g0hOLcGgiPlxc9FC8mAyrgC.jpg');

        texture.wrapS = THREE.RepeatWrapping;

        texture.repeat.set(2, 2); // 水平和垂直各重复5次
       g ou z ou zg ou z ou zgou
        // 3. 创建带纹理的材质
        const material = new THREE.MeshBasicMaterial({ 
            map: texture, // 将纹理应用到材质
            side: THREE.DoubleSide // 双面显示（可选）

        const cube = new THREE.Mesh(geometry, material);
        scene.add(cube);

        // 添加平行光
        const directionalLight = new THREE.DirectionalLight(0xffffff, 0.8);
        directionalLight.position.set(5, 5, 5);
        scene.add(directionalLight);
        
        // 动画循环（让立方体旋转）
        function animate() {
            requestAnimationFrame(animate);
            cube.rotation.x += 0.01;
            cube.rotation.y += 0.01;
